As one of the three royal centres of the Kathmandu Valley in the Nepalese Himalayas, Bhaktapur is a thriving city with some 40,000 inhabitants. Over almost two millenia, its original inhabitants of the valley, the Newars, have shaped a unique urban culture that preserved a pre-industrial lifestyle until the middle of the twentieth century. In these rituals, the supernaturals and humans act collectively to ensure the continuity of time and space. Among the many festivals of the year, ten occasions are selected. Moreover, the ritual of the Navadurgā Deities leaves an imprint on the spatial and temporal integrity of the urban realm over a period of nine months.
